摘要:
While a plurality of cellular mobile communication systems have their respective service areas regionally overlapping each other in part, a mobile station is configured to perform a standby for calling or communication while selecting one of the plural systems in the overlapping areas, and is arranged as follows: the mobile station preliminarily stores cell information notified of by a base station and indicating whether the mobile station is transferable to each surrounding cell while maintaining the current system; when the arrival of transfer timing to a surrounding cell is detected, the mobile station extracts the information about the pertinent cell and judges whether the surrounding cell is a transferable cell, based on the cell information; when the surrounding cell is a transferable cell, the mobile station transfers to the surrounding cell; when the surrounding cell is not a transferable cell, the mobile station directly transfers to a cell of a different system. This makes it feasible to decrease communication down time and decrease power consumption of the mobile station.

A communication path switching system comprises a wireless base station (21) having a function of wireless communication with a mobile station (11) and a function of relaying data transmitted from the mobile station over a wireless communication path; and plural transmission apparatuses (41, 841) having a function of wired communication with the wireless base station and capable of establishing respectively a wired communication path to be used to relay the data transmitted from a mobile station toward another mobile station. One wired communication path from the wireless base station (21) to one transmission apparatus (841) is switched to another wired communication path from the wireless base station (21) to another transmission apparatus (41) without re-establishing a wireless communication path between the mobile station and the wireless base station.

A mobile communication method according to the present invention includes step A of notifying, by a radio base station NodeB01, a radio network controller RNC01 of location information of the radio base station NodeB (location code: bbb), step B of notifying, by the radio network controller RNC01, an exchange station MSC/SGSN of the location information of the radio base station NodeB (location code: bbb) when a mobile station UE starts communication via the radio base station NodeB and the radio network controller RNC01, and step C of controlling each session of the communication by the exchange station MSC/SGSN based on the location information of the radio base station NodeB (location code: bbb).
摘要:
A radio base station monitoring method includes (A) a first radio base station detecting a second radio base station having newly detected a common control channel and a second radio base station having stopped detecting the common control channel as second radio base stations with a change, (B) the first radio base station notifying a network device of information about the second radio base stations with a change, and (C) the network device using information about second radio base stations associated with the first radio base station and the information about the second radio base stations with a change, which has been notified, to stop the operation of at least one of the first radio base station or the second radio base stations.
